Delaware County Contours: This dataset is 2018 two foot contours for Delaware County. It is in File Geodatabase format. I don’t know what they represent but I believe contours can represent continuous things like elevation, temperature, precipitation, pollution, or atmospheric pressure.
Create a new folder on the external drive you have been using for the GTK ArcGIS Pro tutorial. Call the new folder Delaware GIS Data. Download (to the Delaware GIS Data folder) (as .shp files) these three data sets: Parcel, Street Centerline, and Hydrology (search for this last dataset on the Delaware site if you don’t see it in the list). Create a new ArcGIS Pro project and open these three layers. Create a map that shows all three and save a screenshot and include it in your weekly posting.
